Los Angeles Class submarines built since 1982 are equipped with a vertical launch missile system with twelve launch tubes. The submarine is fitted with a Raytheon CCS Mark 2 combat data system. This is to be replaced with a further development, the Raytheon AN/BYG-1 Combat Control System, also to be fitted on USN Virginia and Seawolf classes and Australian Collins Class submarines. The first system will be fitted on SSN68 Los Angeles in late 2005.

The submarine is armed with both the land-attack and anti-ship version of the Tomahawk missile from Raytheon. The land-attack Tomahawk has a range of 2,500km. A TAINS (Tercom Aided Inertial Navigation System) guides the missile towards the target flying at subsonic speed at an altitude of 20m to 100m. Block III improvements include an improved propulsion system and Navstar Global Positioning System (GPS) guidance capability. Tomahawk can be fitted with a nuclear warhead which is not normally carried on the Los Angeles class. The anti-ship Tomahawk missile is equipped with an inertial guidance and an active radar and anti-radiation homing head. The range is up to 450km.

First underwater launch of the new Raytheon Tactical Tomahawk Block IV missile with a live warhead took place from USS Tucson (SSN 770) in July 2003. Block IV includes a two-way satellite link that allows reprogramming of the missile in flight and transmission of Battle Damage Indication (BDI) imagery. The missile entered service with USN surface ships in September 2004.
